The Guardian, Times and the online edition of the Telegraph report on at attack yesterday from Syria, which struck an Israeli civilian vehicle, killing a 15 year-old boy. Sporadic gunfire has spilled over into Israel from the fighting in Syria on a number of previous occasions, but Israel has invariably responded in a limited fashion, in order to remain uninvolved with the Syrian conflict. Yesterday’s incident was the first time that an Israeli had been killed in what Israeli security officials believe was a deliberate attack by the Syrian army. Israel responded by initially striking the source of fire. However, the Telegraph online this morning reports targeted Israeli air strikes which hit nine Syrian military positions overnight.

Meanwhile, the operation to locate three Israeli teenagers who were kidnapped in the West Bank 10 days ago continues. The Metro says that two Palestinians were killed over the weekend in clashes with Israeli security forces. The Independent and Independent i both report that Palestinian Authority (PA) President Mahmoud Abbas finds himself in a quandary, backing and aiding Israel’s operation to find the youngsters, which is proving increasingly unpopular on the Palestinian street. Writing in the Telegraph, Alan Johnson says that Palestinians face a “fateful decision” over the kidnappings, with their response representative of a choice between compromising for the sake of peace or a never-ending resistance.

The military campaign being waged by Sunni Jihadist group ISIS in Iraq is also covered widely. ISIS apparently made further gains over the weekend in the Syrian and Jordanian border areas. Amid speculation regarding potential US engagement in the conflict and possible coordination with Iran, the Telegraph mentions that Israel’s Prime Minister Benjamin Netanyahu has warned the United States that both ISIS and Iran are its enemies. The Independent and Independent i both say that US officials suspect Iran is using the situation in Iraq as leverage for concessions in nuclear talks with the West. Writing in the Times, Melanie Phillips warns that the West must not underestimate the danger posed by Iran. Meanwhile, the Guardian online reports that parents of UK teenagers who have joined ISIS have condemned their actions and pleaded for them to return home.

The online editions of the Guardian and Times both report that US Secretary of State John Kerry this weekend became the highest ranking world official to visit Egypt since the election of President al-Sisi and that Kerry warned him against “polarising tactics” in suppressing the opposition.

In the Israeli media, Israel Hayom leads with the Israel Air Force operation against military targets in Syria last night, which was launched after an attack from Syria killed a 15 year-old Israeli boy who was travelling with his father in a civilian vehicle. It is also a major item in Haaretz. Meanwhile, in Maariv, Orr Heller speculates over whether Hezbollah was behind yesterday’s attack. Hezbollah, a strong ally of Syria’s president Assad, has become increasingly active in Syria near the border with Israel during the past several months.

Maariv also reports comments made by the IDF Spokesman’s Office, who said that the three teenagers kidnapped 10 days ago are assumed to still be alive. Haaretz says that the operation to locate the abducted youngsters is on the verge of exhausting itself. Israel Radio news reports that at least 80 properties were searched by IDF troops last night in Hebron, Jenin, Nablus and Tulkarm as part of the ongoing efforts.

Yediot Ahronot also reports prominently on the interception of a Gaza man who infiltrated into Israel over the weekend, armed with a hand grenade near an Israeli community. Yossi Yehoshua says that had he not been apprehended and instead carried out an attack, it could have proven “a strategic game-changer for Israel.”
